Comprehensive Characterization of Photocatalyst

The crystalline structure of the
photocatalyst was characterized with an X-ray diffractometer (MAC
Science, MXP18, Cu Kα). The morphology and crystalline structure
of the photocatalyst were observed with a high-resolution transmission
electron microscope (JEOL, JEM-3000F, 300 kV). The band gap of the
photocatalyst was determined with UV–vis spectroscopy (Hitachi,
U-2800). EDX spectroscopy (Oxford 6587, Oxford Instruments) was conducted
to determine the elemental composition of the photocatalyst. The size
distribution of the NC suspension was determined with dynamic light
scattering spectroscopy (Malvern ZEN1600), in which DI water was used
as the solvent. The PL spectra were recorded with a fluorescence spectrometer
(Hitachi F-4500). The cell images were observed and taken using an
inverted microscope (Olympus CKX41).

By laser diffractometry, particle size was measured using a nano-size particle analyzer (Zen 1600 Malvern USA) in the range between 0.6 and 6.0 μm, under such conditions such as having particle refractive index 1.590, particle absorption coefficient 0.01, water refractive index 1.33, viscosity—cP, Temperature-25 °C and general calculation model for irregular particles. About 10−15 measurement cycles of 10 s each were taken and the data obtained were averaged by the respective instrument preloaded software (DTS, version 5.00 from Malvern) [38 (link)].

Particle size of the PR-GO nanosheets was measured by laser diffractometry using a nano size particle analyzer (Zen 1600 Malvern USA) in the range between 0.6 nm and 6.0 μm. Transmission Electron Microscopy was performed on a Tecnai G² spirit Biotwin (FP 5018/40), operating at an accelerating voltage of 80 kV. XRD measurements of PR-GO was taken with a PW 3040/60 PANalytical X-ray diffractometer that operated at a voltage of 45 KV and current of 30 mA with Cu Kα radiation (λ 1.54443 Ǻ). The diffracted intensities were recorded from 35° to 90° 2θ angles. EDX analysis was carried out with a Hitachi S 3400N, Japan, to identify the elemental compositions of the particles. The polysaccharide (PS), GO and PR-GO, were all analysed by Fourier transform infrared (FTIR) spectroscopy (Shimadzu 8400S fourier transform infrared spectrophotometer). The system worked in a diffuse reflectance mode at a resolution of 4 cm^-1 in KBr pellets. The scanning data were obtained from the average of 50 scans in the range of 4000 to 400 cm^-1. Raman spectra was monitored using 1.96 eV (633 nm) line of a He Ne laser in HORIBA-JOBIN-YVON Lab RAM HR 800 instrument by placing the sample solution into a semi-micro stopper cuvette with an exposure time of 1 s.

The formation of gold nanoparticles was confirmed by the UV-Vis spectrophotometer (Hitachi 330 spectrophotometer) at 1 nm resolution only after the color change. The size of the nanoparticles was first measured by laser diffractometer (Zen 1600 Malvern USA) and then by Atomic Force Microscopy (AFM) using Nanoscope® 111A Veeco Multimode, USA. The characterization was done in tapping mode (NP10) with a silicon probe over scan sizes of 10 µm. The morphology of the nanoparticles was confirmed by Transmission Electron Microscopy (FP 5018/40, Tecnol G² Spirit Bio TWIN). The XRD spectra were recorded from 30° to 80° 2θ angles using X-ray diffractometer (Seifert XDAL 3000) with CuK_α radiation operated at 45 kV and 30 mA. The FTIR (Fourier Transform Infrared) spectroscopy (Shimadzu FTIR 8400S) was used to obtain the information about the functional groups with which the nanoparticles were stabilized.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
